Expected Result

text.html is included correctly

Debug Information

• if I remove zhtml from pom.xml, the HTML can be included correctly.
• could be caused by org.zkoss.zsoup.parser.XHtmlTreeBuilder

Alternatives

1. Defer

    <include src="text.html" mode="defer"/>

2. Refined html fragment (head/body should be stripped)

<div>

<h2>title</h2>

<p>
    some text in an HTML file
</p>
</div>

3. include a complete page

using <iframe/>
